[en] We report the discovery by the CoRoT satellite of a new transiting giant planet in a 2.83 days orbit about a V = 15.5 solar analog star (M_* = 1.08 ± 0.08 M_ȯ, R_* = 1.1 ± 0.1 R_ȯ, T[SUB]eff[/SUB] = 5675 ± 80 K). This new planet, CoRoT-12b, has a mass of 0.92 ± 0.07 M[SUB]Jup[/SUB] and a radius of 1.44 ± 0.13 R[SUB]Jup[/SUB]. Its low density can be explained by standard models for irradiated planets. The CoRoT space mission, launched on December 27, 2006, has been developed and is operated by CNES, with the contribution of Austria, Belgium, Brazil, ESA (RSSD and Science Program), Germany and Spain.
